Rules
Governing Travel Across the Abyss

The following rules are established as guidelines for how individuals
may traverse the Abyss or Abyssal barriers. There are only a few ways to
cross the Abyss, as detailed below:

Tir'na Nog-th

Amber's reflection in the sky is in fact a mobile Shadow that possesses
enough reality to survive within the depths of the Abyss. In the past,
Cerridwen's magical abilities enabled her to find Shadows and people
adrift in the Abyss, although she usually charged a stiff fee for
transport.

Abyssal Demons

One can be ferried across the Abyss by an Abyssal Demon, but such demons
usually require the sacrifice of a creature of Amberite blood. Travel
also tends to be rather slow.

Abyssal Initiates

The powers Abyssal Shadowwalk,Abyssal Gate, and Abyssal
Tunnel can enable an Abyssal Initiate to traverse the Abyss, though
the Abyssal Shadowwalk ability tends to be very slow.
Unfortunately, none of these powers allow the Initiate to transport
non-Abyssal characters through the Abyss.

Shadow Constructs

It is possible to build a Shadow construct that can move through Shadow.
Essentially, building a mobile Shadow construct enables one to cross the
Abyss, though rather slowly. The minimal cost for such a Shadow is 5
points (Personal Shadow: 1; Control of Destiny: 4), and the character
building such a Shadow must have some knowledge of advanced sorcery and
conjuration.

Bodiless Travel

The Ty'igha seem to be able to cross the Abyss by abandoning their
physical bodies, but it has yet to be determined whether or not this could
be used to enable an ordinary individual to make such a crossing.

The following powers do not enable one to cross the Abyss:

Trump

Pattern

Logrus

Magic

Jewel of Judgment

Likewise, one cannot use the Pattern Lens, magical scrying, Logrus
Sight, or any similar powers to view a person or place across the Abyss.
Jewel Initiates seem to be able recognize the relative direction of the
Jewel from their present location...despite Abyssal barriers, but this
does not allow the Initiate to draw upon the powers of the Jewel.
